QTR-HD-09A Reflectance Sensor Array: 9-Channel, 4mm Pitch, Analog Output Category_Electronics/Misc Items 8mm display area

8mm display area

There are two possible hardware interface options:

communicate with phones (say for payment processing)

the SMA connector footprint is included in the design so that you can manually solder it to the board for your application

It operates from 2. 9 V to 5. 5 V and offers dimmable brightness control independent of the supply voltage and separate controls for the odd and even emitters. In general, the closer the object, the higher the contrast
